Four comments about today's strip:
1. Dares are weird. I guess I can sort of understand them in the context of a game like T or D, where there's a sort of expected reciprocity, but the idea that you can "dare" someone to do something they don't want to do, and that means that their reticence is now reframed as cowardice... it's the sort of bizarre tradition an alien race would follow religiously, so that you could base a Star Trek episode around it.
2. Social constructs with sexual or intimate obligations of any sort (kissing under mistletoe, those sex coupons or body part/action dice you get at novelty shops, spin the bottle, etc.) are also weird. Either the person you're using it on already wants to kiss you (in which case, they should be doing it anyway), or they don't... and, if they don't, either they'll just ignore the social construct (rendering it meaningless), or they'll feel pressured enough to go along with it against their will, which no one is going to enjoy. It just seems either pointless or monstrous to me, with not much in the way of middle ground.
3. Contrary to Max's statement (and the assumption of most of our society), I'd like to mention that watching two hot chicks make out is not necessarily every straight guy's fantasy. Everyone is different. I, personally, have never been particularly aroused by depictions of kissing (not on the mouth, anyway), regardless of the gender of the participants.
4. Yes, as a matter of fact, I am under the impression that three people, hanging out in their apartment, sitting on one couch looking in the same direction, sharing one mixed drink, not playing any music, and having a discussion about menstrual periods and the nature of what constitutes a dare is a perfectly valid "party".
I have plenty of friends.
